The 6SL3520-0XM00-7AA0 is the value-oriented entry point into the SINAMICS G115D distributed drive range. It delivers the same 0.75 kW from the same fanless FSA frame as the AB0 and AF0 variants — the same mechanical robustness, same IP65/IP66 enclosure, same PROFINET and EtherNet/IP connectivity. What it omits is the integrated C2 EMC line filter and the PROFIsafe safety layer, making it the most cost-effective choice for installations where EMC filtering and safety architecture are already handled upstream.

When does the AA0 variant make sense?

The AA0 is the right selection when your installation already addresses EMC compliance at the panel or site level — for example, when the power distribution system includes a central line filter, or when your application does not require C2-level conducted emissions control. It is also suitable when your safety architecture uses external safety relays or a separate safety PLC rather than PROFIsafe for the STO function. The fail-safe digital input (F-DI) still provides certified STO to SIL 2 / PL d.

What is the G115D wall-mounted installation footprint?

The FSA frame measures 380 mm wide × 156 mm high × 129 mm deep and weighs approximately 6.2 kg. It mounts directly to a machine frame or conveyor support structure using four M5 bolts. Minimum clearance requirements: 200 mm on the wiring side and 150 mm on the non-wiring side for adequate convection cooling. The drive can be mounted in any orientation, though some positions require output current derating.

Frequently Asked Questions

Can I add a C2 filter to the AA0 variant after installation?

No. The C2 line filter is factory-integrated into the AB0 and AF0 variants and cannot be retrofitted. If C2 compliance is required, select the AB0 suffix. An external filter can be added upstream of the AA0, but this adds panel space, wiring complexity, and cost — often exceeding the price difference to the AB0 variant.

Does the AA0 variant support the same motor types as the AB0 and AF0?

Yes. Motor compatibility is identical across all G115D variants: SIMOGEAR 2KJ8 geared motors, standard Siemens asynchronous motors, synchronous reluctance motors, and permanent-magnet synchronous motors. The suffix code only affects the EMC filter and safety communication — not motor control capability.
